Abstract

Abstract

A self-integrating Rogowski coil is designed and employed to detect the output current of a Marx generator.The Rogowski coil is calibrated with a 1.0kA pulsed power generator which is driven by a capacitor.One TEM chamber is used to obtain the frequency response of the square-wave for the coil.The experiment result can agree with the circuit simulation result very well.The response time of the coil is about 16.0ns.During the experiment the Marx generator output current waveform decays very quickly at the tail of the pulse and the base line is distorted.This is analyzed by the circuit simulation model and the simulation results suggest that the distortion could be eliminated by adjusting the time constant of the RC integrator.The experiment results are consistent with theoretical analysis, and the improved coil can response correctly.
